Abstract

The invention discloses a sweet potato seedling growing method suitable for the center area of Guizhou. The method comprises the steps of (1) soil preparation and seed bed making, (2) seed bed and greenhouse sterilization, (3) sparse arrangement of mulching films, (4) light temperature management, (5) water and fertilizer management, and (6) seedling picking. The sweet potato seedling growing method suitable for the center area of Guizhou is selected and designed according to the conditions of the center area of Guizhou, operation at all seedling growing stages is optimized, all steps are selected reasonably, and thus seedling emergence speed, the output of seedlings and the quality of the seedlings of sweet potatoes can be effectively improved.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for raising sweet potato seedlings suitable for central Guizhou. Background technique [0002] Guizhou Province currently has an area of ​​3.8 million mu of sweet potatoes. Central Guizhou is the main production area of ​​sweet potatoes in this province. In the past, the seedling cultivation methods in this area used the open-field film-covering technology. The open field cover film technology is easy to operate and less investment, but the emergence speed is slow, the amount of emergence is small, and the seedling quality is poor. Contents of the invention [0003] The purpose of the present invention is to provide a method for raising sweet potato seedlings suitable for the central Guizhou area, which solves the problems of slow emergence of sweet potato seedlings, less seedling emergence and poor seedling quality in the central Guizhou area. [0004] The pres...
